Last month, I got a great deal on bright blue Eames shell chair, but the swivel base was just too office-y for my taste. Over the weekend, I switched out the old base for a black wire rocker base with walnut runners. So much better!
By the way, I personally find the vintage fiberglass Eames shells to be FAR more attractive than the newer polypropylene reproductions made by Vitra. Yes, they’re licensed by Herman Miller, but they just aren’t the same thing. If you live in the U.S., it’s very easy to get vintage Eames shell chairs for less than $50 apiece. Patience is key, but they are absolutely not as unattainable as Vitra would have you believe—there’s no need to pay $229 for a chair ($399 for a rocker!) that doesn’t even look like its supposed to (trust me on this; if you saw a vintage Eames shell next to a new one, you would think the new one is a cheap knockoff). If you find a shell without a base (or with a base you don’t like), there are several people who sell reproduction bases in all styles on eBay. For my money, a vintage shell in all its fiber-rich glory is way more satisfying than a completely smooth piece of new, molded plastic, even if I have to do a little extra work to get it how I want.
